If you want to produce some nice maps (or analyze further your data outside R), I suggest you to export the probability surface (as raster), as well. You can use something like (you have to work a little bit on the code, i am copying it from a longer function):
asc<-ud[[i]][[1]] res <- asc2spixdf(asc) writeGDAL(res, paste(path,name, sep=""), drivername = "GTiff", type = "Float32") Ferdi >---------------------------------------------------------------------- > >Message: 1 >Date: Tue, 24 Nov 2009 12:17:16 -0500 >From: Corrie Curtice [email protected]> >Subject: [AniMov] Exporting kernel home range utilization distribution > to an ESRI shapefile >To: [email protected] >Message-ID: > [email protected]> >Content-Type: text/plain; charset=ISO-8859-1 > >Hello, > >Is there a straightforward method for exporting a kernel home range >utilization distribution produced by kernelUD to an ESRI shapefile?
